𝑦=𝑥2 −6𝑥−27
To factor this equation, we need to find two numbers that multiply to -27 and add up to -6. These numbers are -9 and 3.
So, we can rewrite the equation as:
y = (x - 9)(x + 3)
This is the factored form of the equation.
To factor the equation 𝑦=𝑥^2−6𝑥−27, we need to find two numbers that multiply to -27 and add up to -6.
The factors of -27 are (-1, 27), (1, -27), (-3, 9), (3, -9), (-9, 3), and (9, -3).
Out of these pairs, the numbers -3 and 9 add up to -6.
Therefore, we can factor the equation as follows:
𝑦= (𝑥−3)(𝑥+9)
